PROBLEM TO BE SOLVED: To provide a float type liquid level detection device in which a magnet float does not sink in a detection target liquid even when having a specific gravity higher than that of the detection target liquid and an influence of rippling of a liquid surface of the detection target liquid can be suppressed.SOLUTION: The float type liquid level detection device 10 has a magnet float 14 having magnetism intubated so that the magnet float is moved vertically along an outer periphery of a substantially perpendicularly arranged stem 12, and detects a change in surface level of a detection target liquid by the change in position of the magnet float and includes repulsing means 20 for generating a repulsive force in the lower surface side of the magnet float and sucking means 22 for generating a sucking force on the upper surface side of the magnet float. |
